something that happens, an occurance or event. it is used specifically in inquisition, and is featured in the motion picture Joe Dirt.
A bro, or brosky, will walk through your front door unbeknownst to you with a twelve pack of rolling rock or corona, at which point you exclaim: "What's crappening?!"
When something crappy happens.
I can't believe this is crappening to me right now.
(1)Shitty stuff that happens on a daily basis OR (2)funny stories involving poo
(1)Waking up late, traffic, spilling coffee on your keyboard, getting ridiculous assignments from your boss. These could all be on your list of crappenings OR (2)that wonderful story your mom tells every year at Christmas about how she caught you fingerpainting with feces when you were two.
